Partitioning data in a clustered database environment

ABSTRACT

A system can include a server, various application servers, various database servers, and a system database. The application servers can be divided into application server groups that each include an application server. The server receives data from a data source and the data includes a source identifier and a key identifier associated with the data source. The server determines a particular application server group that is associated with the data source based on the source identifier of the data source and transmits the data from the data source to an application server of the application server group. The application server determines a particular database server associated with the application server group and transmits the data to the database server, which determines a particular partition of a system database in which to store the data based on the key identifier of the data source.

CROSS-REFERENCE TO RELATED APPLICATIONS

This is a continuation of U.S. patent application Ser. No. 15/925,257 entitled “Partitioning Data in a Clustered Database Environment” filed Mar. 19, 2018 (allowed), the contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates generally to data sharding. More specifically, but not by way of limitation, this disclosure relates to partitioning data in a clustered database environment, which can improve the scalability of the environment and performance of devices in the clustered database environment.

BACKGROUND

In a clustered database environment, various servers or other devices may access one or more datasets. In some existing clustered database environments, the servers or devices may share access to the datasets, which can cause various technical issues in the environment such as cluster wait or server contention events that can occur when one or more servers or other devices in the environment attempt to access the same dataset simultaneously.

In some existing clustered database environments, cluster wait or server contention events can prevent, delay, or otherwise impact the ability of one or more servers or devices in the environment to perform various operations such as by preventing a server from accessing or processing a dataset when another server is accessing or processing the same dataset. Preventing or delaying one or more of servers or devices from performing operations can waste network resources or the server or device's computing resources while the server or device is prevented or delayed from performing operations. Moreover, such technical problems in existing clustered database environments may be amplified on interconnect traffic in a high availability clustered database environment in which various servers or devices are communicatively connected, receive data in a random fashion (e.g., from a load balancer device), and may attempt to simultaneously access the same data. Furthermore, such technical problems in existing clustered database environments may prevent the environment from being scaled out (e.g., prevent the addition of additional database servers) or may be further amplified if the database environment is scaled out.

Thus, existing clustered database systems and methods present disadvantages such as, but not limited to, those discussed above and may be unable to manage or analyze large, complex data sets. For these and other reasons, improved techniques for managing data in a clustered database environment and improved clustered database systems are therefore desirable.

DETAILED DESCRIPTION

Certain aspects and features of the present disclosure relate to partitioning data in a clustered database environment, which can improve the scalability of the environment and the performance of devices in the environment. As described above, existing clustered database environments and systems may include various devices (e.g., servers, databases, etc.) that share access to one or more datasets, which can cause cluster wait or contention events that may occur when or more devices simultaneously attempt to access the same data set. Certain examples described herein address these issues by partitioning data in a clustered database environment based on an identifier of a data source such that data from a data source is consistently transmitted to, and processed by, a particular device (e.g., server or database) or group of devices, which can improve the scalability of the environment and performance of devices in the environment.

In one example, a clustered database environment or system includes a server, various application servers, various database servers, and a system database. In this example, the various application servers can be divided into groups (e.g., farms) and each group of application servers can be associated with (e.g., communicatively connected to) a particular database server. In some instances, a number of application server groups in the environment can be based on a number of database servers in the environment and a number of application servers in each group can be based on the number of application server groups. For instance, if the environment includes three database servers and twenty-four application servers, the application servers can be divided into three application server groups that each include eight application servers. In another example, each application server group can include any number of application servers. For instance, each application server group can include a different number of application servers.

Continuing with this example, the server can be communicatively coupled to one or more data sources and can receive data from the data sources. An example of a data source can include a meter device for measuring consumption of a resource, such as electricity, gas, water, etc. A data source may measure or receive (e.g., obtain) data, optionally store the data, and communicate the data to the server. The data can include information measured or received (e.g., obtained) by the data source, along with a source identifier or a key identifier associated with the data source. A source identifier associated with a data source can be an identifier that can be used to identify the data source and route data from the data source to a particular group of application servers, an application server, or a database server. As an example, a source identifier associated with a meter data source or device can be a meter identifier. A key identifier associated with a data source can be an identifier that can be used to route data from the data source to a particular portion or partition of the system database. As an example, if a data source is a meter device, a key identifier associated with the meter device can be a portion of a meter identifier of the meter device that corresponds to a particular partition of the system database.

The server can include a processor and a memory that includes a database (e.g., a lookup table) and the server can determine a particular route for data received from the various data sources. For instance, the processor can determine a routing identifier associated with a data source based on a source identifier of the data source using one or more formulas, algorithms, methods, etc. In another example, the processor can access the database to determine a routing identifier associated with a data source based on a source identifier associated with the data source. The routing identifier can be used to determine a particular route for data received from the data source. For instance, the database can include data indicating source identifiers associated with various data sources and a routing identifier associated with each source identifier. A routing identifier can indicate a particular group of application servers, an application server, or a database server associated with a data source. For instance, a routing identifier can be used to determine a particular group of application servers or a particular database server of the environment that can receive or process data from a data source. In this example, the server receives data from the data source, along with the source identifier associated with the data source and the processor of the server can determine a routing identifier associated with the source identifier of the data source. In this example, the server can transmit the data from the data source to the particular application server group associated with the data source, in response to determining the routing identifier associated with the data source.

In this example, an application server of the application server group associated with the data source can receive data from the server and process or analyze the data. The application server can then transmit the processed data to a particular database server associated with the application server group. The database server can include a processor and a memory that includes a database. The processor of the database server can access the database to route data received from the application server to a particular portion or partition of the system database. For instance, the system database can be partitioned (e.g., divided) based on key identifiers associated with various data sources. As an example, each portion or partition of the system database can be associated with a key identifier of a particular data source. In this example, the database of the database server can include data indicating key identifiers associated with various data sources and a portion of the system database associated with each key identifier. The database server can use the database to route data obtained from the data source to a particular portion of the system database that corresponds to the key identifier of the data source.

As an illustrative example, a gas meter measures or receives data and transmits the data to a server, along with a source identifier (e.g., a meter identifier) and a key identifier (e.g., the last two digits of the meter identifier) of the gas meter. The server can determine a routing identifier associated with the meter based on the meter's source identifier and use the routing identifier to determine a particular group of application servers that can process data from the gas meter and a particular database server associated with the group of application servers. An application server of the group of application servers can process the data from the gas meter device and transmit the processed data to the database server. The database server can use the key identifier of the gas meter device to determine a portion or partition of a system database in which to store the data. For instance, the system database is partitioned into various portions and each portion of the system database corresponds to a key identifier of a particular gas meter device. In this example, the database server transmits the data from the gas meter device to the system database to be stored in the portion of the system database associated with the key identifier of the gas meter device.

In this manner, data obtained from a data source can be routed to a particular group of application servers and database server, which can prevent other application servers or database servers in the clustered database environment that are not associated with or assigned to the data source from accessing or processing data from the data source. Furthermore, data from the data source can be stored in a particular portion of a system database. In some instances, routing data from one or more data sources as described herein can prevent various devices in a clustered database environment from sharing access to the same dataset, which can mitigate or eliminate cluster wait or contention issues in the clustered database environment and improve the scalability of the environment and the performance of devices in the environment.

These illustrative examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts. The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions are used to describe the illustrative examples but, like the illustrative examples, should not be used to limit the present disclosure.

FIG. 1 is an example of a data partitioning system 100 according to one example of the present disclosure. The system 100 can be any type of system in which data can be partitioned or sharded (e.g., a system for partitioning or dividing data among or within servers, databases, or devices). In some instances, the system 100 can be a clustered database system such as a system that includes various servers (e.g., nodes) that can perform various operations on data received by the system 100.

In the example depicted in FIG. 1, the system 100 includes one or more servers 102 a-d, application server groups (e.g., farms) 104 a-c, database servers 106 a-c, and a system database 108. In this example, the application server groups 104 a-c include various application servers 110 a-1. Each server 102 a-d, database server 106 a-c, or application server 110 a-1 can be any computing system (e.g., device) or storage device and can include one or more components. For example, each server 102 a-d, database server 106 a-c, or application server 110 a-1 can include a processor, a bus, a database, a memory, input/output interface components, a display device, communication device, etc.

In some examples, a number of application server groups 104 a-c in the system 100 can be based on a number of database servers 106 a-c in the system 100 and each application server group 104 a-c can be associated with (e.g., communicatively coupled to) a particular database server 106 a-c. For instance, in the example depicted in FIG. 1, the system 100 includes three database servers 106 a-c and three corresponding application server groups 104 a-c associated with a particular database server 106 a-c. In this example, the application server group 104 a is communicatively coupled to the database server 106 a, application server group 104 b is communicatively coupled to the database server 106 b, and application server group 104 c is communicatively coupled to the database server 106 c. In some examples, a number of application servers 110 a-1 in each application server group 104 a-c can be based on the number of application server groups 104 a-c in the system 100. For instance, in the example depicted in FIG. 1, the system 100 includes twelve application servers 110 a-1 and three application server groups 104 a-c that each include four application servers. In another example, each application server group 104 a-c can include any number of application servers 110 a-1. For instance, each application server group 104 a-c can include a different number of application servers 110 a-1.

In some examples, one or more data sources 10 a-c can be communicatively coupled to one or more devices or components of the system 100 (e.g., servers 102 a-d). In another example, the data sources 10 a-c can be communicatively coupled to one or more remote devices or servers. For example, the data sources 10 a-c can be communicatively coupled to one or more other data sources, meter devices, network devices, etc. In some instances, the data sources 10 a-c may communicate (e.g., transmit and receive data) with the one or more data sources, meter devices, or network devices via a wireless mesh network. Further, in some examples, a network device, such as collector device, may facilitate communication between the data sources 10 a-c and one or more servers (e.g., the servers 102 a-d).

In some examples, each server 102 a-d can be communicatively coupled to one or more data sources 10 a-c and can receive data from the data source. An example of a data source 10 a-c can include a meter device for measuring consumption of a resource, such as electricity, gas, water, etc. A data source 10 a-c may measure or receive (e.g., obtain) data, store the data, and communicate the data to a server 102 a-d. The data can include information measured or received (e.g., obtained) by the data source 10 a-c, along with a source identifier or a key identifier associated with the data source 10 a-c. A source identifier can be any data or information that can be used to identify the data source 10 a-c and route data from the data source 10 a-c to a particular group of application server group 104 a-c, application server 110 a-1, or database server 106 a-c. As an example, a source identifier of a meter data source or device can be a meter identifier. A key identifier of a data source 10 a-c can be any data or information that can be used to route data from the data source 10 a-c to a particular portion or partition of the system database 108. As an example, a key identifier of a meter device can be a portion of a meter identifier of the meter device that corresponds to a particular portion or partition of the system database 108.

Each server 102 a-d can include a processor and a memory that includes a database (e.g., a lookup table). The processor can be communicatively coupled to the memory (e.g., via a bus). The memory of the server 102 a-d can be any type of memory device that retains information when powered off. In some examples, a server 102 a-d can receive data from a data source and the processor of the server 102 a-d can determine a particular route for the data received from the data source. As an example, the processor of the server 102 a can access the database to determine a particular route for the data received from the data source 10 a-c. For instance, the database of the server 102 a can include data indicating source identifiers associated with various data sources 10 a-c and a routing identifier associated with each source identifier (e.g., in a lookup table 112). In some examples, the server 102 a can obtain or receive data indicating the various source identifiers and routing identifiers (e.g., from another device or via user input). A routing identifier can indicate a particular application server group 104 a-c, application server 110 a-1, or database server 106 a-c associated with a data source 10 a-c (e.g., assigned to the data source to receive or process data from the data source). For example, in the example depicted in FIG. 1, each server 102 a-d can include a lookup table 112 that includes data indicating various source identifiers 114 a-e (e.g., various meter identifiers) and routing identifiers 116 a-e (e.g., values or any other identifier) associated with each source identifier 114 a-e. In this example, each routing identifier 116 a-e indicates the particular application server group 104 a-c or database server 106 a-c assigned to each source identifier 114 a-e to receive or process data from the data source 10 a-c associated with each source identifier 104 a-e. For example, routing identifiers 116 a and 116 d can indicate that source identifiers 114 a and 114 d are associated with (e.g., assigned to) application server group 104 a and/or database server 106 a, routing identifiers 116 b and 116 e can indicate that source identifiers 114 b and 114 e are associated with application server group 104 b and/or database server 106 b, and routing identifier 116 c can indicate that source identifier 114 c is associated with application server group 104 c and/or database server 106 c. Continuing with this example, the server 102 a can receive data from the data source 10 a-c, along with the source identifier 114 a-e associated with the data source 10 a-c and the processor of the server 102 a can access the lookup table 112 to determine a routing identifier 116 a-e associated with the source identifier. In this example, the server 102 a can transmit data from the data source to the particular application server group 104 a-c associated with the data source, in response to determining the routing identifier 116 a-e associated with the data source.

While in the example described above, the lookup table 112 includes data indicating routing identifiers associated with various source identifiers and the processor of the servers 102 a-d can access the lookup table 112 to determine a routing identifier associated with a source identifier of a data source 10 a-c, the present disclosure is not limited to such configurations. Rather, in other examples, the processor of the servers 102 a-d can determine a routing identifier associated with a data source 10 a-c based on a source identifier of the data source 10 a-c without accessing the lookup table 112. For instance, the sever 102 a can receive data from a data source 10 a-c, along with the source identifier 114 a-e associated with the data source 10 a-c and the processor of the server 102 a can calculate or determine a routing identifier 116 a-e associated the source identifier 114 a-e and/or the data source 10 a-c using one or more formulas, algorithms, methods, etc. Furthermore, while in the example described above, the servers 102 a-d include the lookup table 112, the present disclosure is not limited to such configurations. Rather, in other examples, the lookup table 112 may be a part of the servers 102 a-d or may be separate or remote from the servers 102 a-d and the servers 102 a-d can be communicatively coupled to the lookup table 112 to access the lookup table 112.

In some examples, the system 100 can include load balancer devices 118 a-c. Each load balancer device 118 a-c can be associated with a particular application server group 104 a-c and communicatively coupled to the particular application server group 104 a-c and the servers 102 a-d. A load balancer device 118 a-c can be any device configured to determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c associated with the application server group 104 a-c.

For example, the processor of the servers 102 a-d can receive data from a data source 10 a-c and determine an application server group 104 a-c associated with the data source 10 a-c based on a routing identifier as described above. In this example, the memory of the servers 102 a-d can include data indicating a load balancer device 118 a-c associated with each application server group 104 a-c and the processor of the servers 102 a-d can access the memory to determine a particular load balancer 118 a-c associated with the application server group 104 a-c and transmit data obtained from the data source 10 a-c to the particular load balancer device 118 a-d. As an example, the server 102 a obtains data from a data source 10 a and determines that routing identifier 116 a is associated with a source identifier 114 a of the data source 10 a. In this example, the server 102 a can determine that the routing identifier 116 a is associated with the application server group 104 a. Continuing with this example, the server 102 a can determine that a particular load balancer device 118 a is associated with the application server group 104 a and transmit the data to the load balancer device 118 a. The load balancer device 118 a can determine an application server 110 a-d within the application server group 104 a to process or analyze data from the data source 10 a associated with the application server group 104 a. In some instances, the load balancer devices 118 a-c can determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c using various methods or techniques (e.g., in a random manner, based on an availability of an application server 110 a-1 to process data, or any other suitable method or technique). For instance, the load balancer device 118 can determine that the application server 110 a can process data from a data source 10 a-c in response to determining that the application server 110 a has available computing or network resources to process the data (e.g., if the application server 110 a is not performing an operation). As another example, the load balancer device 118 can determine that the application server 110 a can process data from a data source 10 a-c in response to determining that the application server 110 a has more computing or network resources available as compared to the other application servers 110 b-d of the application server group 104 a (e.g., if the other application servers 110 b-d are performing more operations as compared to the application server 110 a).

In some examples, the servers 102 a-d may not communicate directly with the load balancer devices 118 a-c. For instance, the processor of the servers 102 a-d can receive data from a data source 10 a-c and determine an application server group 104 a-c associated with the data source 10 a-c based on a routing identifier as described above. In this example, the processor of the servers 102 a-d can transmit the data from the data source 10 a-c to the application server group 104 a-c associated with the data source 10 a-c. A load balancer device 118 a-c associated with the application server group 104 a-c may receive (e.g., intercept) the data from the servers 102 a-d and determine a particular application server 110 a-1 within the application server group 104 a-c associated with the load balancer device 118 a-c to process or analyze data from the data source 10 a-c. As an example, the server 102 a obtains data from a data source 10 a and determines that routing identifier 116 a is associated with a source identifier 114 a of the data source 10 a. In this example, the server 102 a can determine that the routing identifier 116 a is associated with the application server group 104 a and transmit the data from the data source 10 a to the application server group 104 a. Continuing with this example, the load balancer device 118 a associated with the application server group 104 a can receive (e.g., intercept) the data from the server 102 a and determine an application server 110 a-d within the application server group 104 a to process or analyze the data from the data source 10 a associated with the application server group 104 a.

In some examples, the system 100 may not include load balancer devices 118 a-c. In this example, the servers 102 a-d can be configured to determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c associated with the application server group 104 a-c in substantially the same manner as described above.

In some examples, the application servers 110 a-1 can be communicatively coupled to the servers 102 a-d or the load balancer devices 118 a-c to receive data from the servers 102 a-d or the load balancer device 118 a-c and process or analyze the data. Each application server 110 a-1 can also be communicatively coupled to a particular database server 106 a-c associated with the application server group 104 a-c of the application server 110 a-1. For example, application servers 110 a-d of application server group 104 a can be associated with database server 106 a, application servers 110 e-h of the application server group 104 b can be associated with database server 106 b, and application servers 110 i-1 of the application server group 104 c can be associated with the database server 106 c. The application servers 110 a-1 can process data obtained or received from the servers 102 a-d or the load balancer device 118 a-c and transmit the processed data to a particular database server 106 a-c associated with the application server group of the application server 110 a-1.

For example, each application server 110 a-1 can include a processor and a memory that includes a database. The database of the application server 110 a-1 can include data indicating a particular database server 106 a-c associated with the application server group 104 a-c of the application server 110 a-1. In some examples, the application server 110 a-1 can process data obtained or received (e.g., via the load balancer device 118 a-c or the servers 102 a-d), determine a particular database server 106 a-c associated with the application server group 104 a-c of the application server 110 a-1, and transmit the processed data to the particular application server group 104 a-c. For instance, the application server 110 a can process data received from the load balancer device 118 a or the server 102 a. The processor of the application server 110 can access a database of the application server 110 a and determine that the database server 106 a is associated with the application server group 104 a of the application server 110 a. The application server 110 a can then transmit the processed data to the database server 106 a.

Each database server 106 a-c can be communicatively coupled to an application server 110 a-1 of a particular application server group 104 a-c associated with the database server 106 a-c. The database servers 106 a-c can include a processor and a memory that includes a database (e.g., a lookup table). The processor can be communicatively coupled to the memory (e.g., via a bus). The memory of the database server 106 a-c can be any type of memory device that retains information when powered off. In some examples, a database server 106 a-c can receive data from an application server 110 a-1 associated with the database server 106 a-c and the processor of the database server 106 a-c can route data received from the application server 110 a-1 to a particular portion or partition of the system database 108.

For example, the system database 108 can be partitioned (e.g., divided) based on key identifiers associated with various data sources 10 a-c. As an example, the system database 108 can be partitioned into partitions (e.g., portions) 120, 122, 124 and each partition 120, 122, 124 can be associated with a key identifier of a particular data source 10 a-c. For instance, in the example depicted in FIG. 1, partition 120 can be associated with the key identifier of the data source 10 a-c corresponding to source identifier 114 a such that data from the data source 10 a-c is stored in the partition 120, partition 122 can be associated with the key identifier of the data source 10 a-c corresponding to source identifier 114 b such that data from the data source 10 a-c is stored in the partition 122, and partition 124 can be associated with the key identifier of the data source 10 a-c corresponding to source identifier 114 c such that data from the data source 10 a-c is stored in the partition 124. Thus, in some examples the system database 108 can be horizontally partitioned based on key identifiers associated with various data sources 10 a-c.

In this example, the database of the database servers 106 a-c can include data indicating key identifiers associated with various data sources and a portion of the system database 108 associated with (e.g., assigned to) each key identifier. In some examples, the database servers 106 a-c can obtain (e.g., receive) data indicating key identifiers associated with various data sources 10 a-c and a portion of the system database 108 associated with each key identifier from another device or via user input (e.g., from another device or via user input). The database servers 106 a-c can use the database to route data obtained from a data source 10 a-c (e.g., via a corresponding application server 110 a-1) to a particular portion of the system database 108 that corresponds to the key identifier of the data source 10 a-c such that the data can be stored in the particular portion of the system database 108. As an example, the database server 106 a obtains data from the application server 110 a that includes data from a data source 10 a-c associated with source identifier 114 a, along with the key identifier of the data source 10 a-c. A processor of the database server 106 a access a database of the database server 106 a to determine the particular partition 120 of the system database 108 associated with the key identifier and transmits the data to the system database 108 to be stored in the partition 120 of the system database 108.

In another example, the processor of the database servers 106 a-c can determine a key identifier associated with a data source 10 a-c without accessing the database of the database servers 106 a-c and use the determined key identifier to route data from the data source 10 a-c to a particular portion or partition of the system database 108. For instance, the database server 106 a obtains data from the application server 110 a that includes data from a data source 10 a-c associated with source identifier 114 a. In this example, the processor of the database server 106 a can determine a key identifier associated with the source identifier 114 a without accessing a database of the database servers 106 a-c. As an example, the source identifier 114 a can be a meter identifier of a meter device data source 10 a-c and the processor can use various algorithms, methods, or techniques to determine that the key identifier associated with the source identifier 114 a is a portion of the meter identifier (e.g., the last two digits of the meter identifier). In this example, the processor of the database server 106 a can use the determined key identifier to route data from the data source to a particular partition 120 of the system database 108 associated with the determined key identifier and transmit the data to the system database 108 to be stored in the partition 120.

In some examples, the system database 108 can additionally or alternatively be partitioned in any suitable manner. For example, the system database 108 can be additionally or alternatively partitioned based on a date, time, or any suitable interval. As an example, data stored in the system database 108 can be additionally partitioned based on a time that the data is obtained or received from a data source 10 a-c such that data obtained from a data source 10 a-c is stored in a particular partition of the system database 108, as described above, and the particular partition is further partitioned based on the time the data is received (e.g., data received from the data source 10 a-c at a particular time can be stored within a sub-partition of the partition). Thus, in some examples, the system database 108 can be vertically partitioned based on any suitable criteria (e.g., based on a date or time) such that data from the particular data source 10 a-c is further stored in a particular sub-partition of the partition. Accordingly, the system database 108 can be horizontally partitioned (based on key identifiers associated with various data sources 10 a-c) and/or vertically partitioned (e.g., based on any suitable criteria).

In this manner, data obtained from various data sources 10 a-c can be routed to a particular group of application servers 104 a-c and database server 106 a-c that can receive or process the data, which can prevent other groups of application servers 104 a-c, application servers 110 a-1, or database servers 106 a-c that are not associated with or assigned to a data source 10 a-c from accessing or processing data from the data source 10 a-c. Furthermore, the data from the various data sources 10 a-c can be processed by the various servers 102 a-d, the load balancer devices 118 a-c, application servers 110 a-1, or database server 106 a-c and stored in a particular portion of a single system database 108. Thus, in some instances, a single system database 108 can be used to store data from various disparate sources that can be processed by various servers or devices, which may obviate the use of multiple databases in the system 100. In some instances, routing data from one or more data sources 10 a-c as described herein can prevent various devices in the system 100 (e.g., the application servers 110 a-1 or database servers 106 a-c) from sharing access to the same data (e.g., from the same data source) or simultaneously attempting to access the same data, which can mitigate or eliminate cluster wait or contention issues in the system 100. In some examples, mitigating or eliminating cluster wait or contention issues in the system 100 can prevent resources of the system 100 from being wasted, such as by preventing one or more application servers 110 a-1, database servers 106 a-c, or any other device in the system 100 from being prevented or delayed from performing operations on data obtained by the system 100.

In some examples, an error may occur in the system 100 (e.g., an error, failure, defect, etc. in one or more devices or components of the system 100). In this example, if an error occurs in the system 100, one or more components of the system 100 can be configured to determine an additional or alternative route for data obtained or received by the servers 102 a-d. As an example, if a defect or an error occurs in the database server 106 a, the application servers 110 a-d associated with the database server 106 a can be configured to determine an alternative route for data obtained or received by the application servers 110 a-d.

For example, FIG. 4 is an example of a data partitioning system according to one example of the present disclosure. In the example depicted in FIG. 4, the application server 110 a can receive data from the load balancer device 118 a or server 102 a and determine or detect that a defect (e.g., a failure) has occurred in the database server 106 a. In this example, the application server 110 a can determine or identify another database server 106 b-c in the system 100 to receive or process the data. For instance, the application server 110 a can determine that the database sever 106 b is available to receive or process data and transmit the data obtained to the database server 106 b instead of the database server 106 a in response to determining that the defect has occurred in the database server 106 a. The database server 106 b can then determine a portion or partition of the system database 108 in which to store the data based on a key identifier of the data source 10 a-c in substantially the same manner as described above. In this manner, data obtained or received by the system 100 can be re-routed if an error or defect occurs in one or more components of the system 100.

Returning to FIG. 1, although FIG. 1 illustrates a particular arrangement of the system 100, various additional arrangements are possible. As an example, while FIG. 1 illustrates a certain number of servers 102 a-d, application server groups 104 a-c, application servers 110 a-1, database servers 106 a-c, and system database 108, the present disclosure is not limited to such configurations. Rather, in other examples, the system 100 may include any suitable number or types of servers 102 a-d, application server groups 104 a-c, application servers 110 a-1, database servers 106 a-c, and system database 108. For instance, in some examples, the system 100 can be scaled out (e.g., scaled out to include additional application server groups, application servers, database servers, or system databases 108). Moreover, while in some examples described above, a data source 10 a-c can transmit data indicating a source identifier or a key identifier associated with the data source 10 a-c to one or more devices in the system 100, the present disclosure is not limited to such configurations. Rather, in other examples, a data source 10 a-c can transmit data to one or more components of the system (e.g., servers 102 a-d) and the data can include information measured or received (e.g., obtained) by the data source 10 a-c, along with a source identifier associated with the data source 10 a-c. In this example, one or more components of the system 100 (e.g., the servers 102 a-d, application servers 110 a-1, database servers 106 a-c, load balancer devices 118 a-c, or system database 108) can determine a key identifier associated with the data source 10 a-c based on the source identifier. For instance, the server 102 a obtains data from a data source 10 a-c associated with the source identifier 114 a. In this example, a processor of the server 102 a can determine a key identifier associated with the source identifier 114 a of the data source 10 a-c. As an example, the source identifier 114 a can be a meter identifier of a meter device data source 10 a-c and the processor can determine that the key identifier associated with the source identifier 114 a is a portion of the meter identifier (e.g., the last two digits of the meter identifier). In this example, the determined key identifier can be used to route data from the data source 10 a-c to a particular partition of the system database 108 associated with the determined key identifier in substantially the same manner as described above. In some examples, using a meter identifier as a source identifier for determining a routing identifier or a key identifier can provide one or more advantages. For example, if the meter identifier is the source identifier of a data source 10 a-c and the key identifier is a portion of the meter identifier, the data source 10 a-c can transmit the measured data, along with data indicating the source identifier, to one or more components of the system 100 (e.g., the servers 102 a-d, application servers 110 a-1, database servers 106 a-c, load balancer devices 118 a-c, or system database 108). In this example, the one or more components can determine or identify a key identifier (e.g., the portion of the meter identifier) based on the source identifier (e.g., the meter identifier)

Furthermore, while in the examples described above, a routing identifier and/or a key identifier of a data source 10 a-c can be determined based on a source identifier of the data source 10 a-c, the present disclosure is not limited to such configurations. Rather, in other examples, a routing identifier and/or a key identifier of a data source 10 a-c can be determined using any suitable method or technique.

For example, FIG. 2 is an example of a data partitioning system 200 according to another example of the present disclosure. In this example, the system 200 includes the servers 102 a-d, application server groups 104 a-c, application servers 110 a-1, database servers 106 a-c, load balancer devices 118 a-c, and system database 108 of FIG. 1. In the example depicted in FIG. 2, the system 200 is scaled out to include additional load balancer device 202, application server group 204, application servers 206 a-d, and database server 208 each of which can be configured in substantially the same manner as the load balancer device 118 a-c, application server groups 104 a-c, application servers 110 a-1, and database servers 106 a-c of FIG. 1, respectively.

In this example, the lookup table 112 of the servers 102 a-d includes various source identifiers 210 a-e (e.g., various meter identifiers) and routing identifiers 212 a-e associated with each source identifier 210 a-e and the lookup table 112 can be used to route data from a data source (e.g., data source 10 a-c of FIG. 1) associated with a source identifier 210 a-e to the load balancer devices 118 a-c and 202, application server groups 118 a-c and 204, application servers 110 a-1 and 206 a-d, and database servers 106 a-c and 208 in substantially the same manner as described above. In some examples, the servers 102 a-d can receive data indicating the source identifiers 210 a-e and routing identifiers 212 a-e (e.g., from another device or via user input) in response to the load balancer device 202, application server group 204, application servers 206 a-d, or database server 208 being added to the system 100 of FIG. 1.

In this example, the system database 108 can be further partitioned based on a key identifier of one or more data sources such that data from the data source can be stored in a particular portion of the system database 108 in substantially the same manner as described above. For instance, the system database 108 can be further partitioned to include partition 214 such that data obtained from a data source associated with application server group 204 and database server 208 (e.g., a data source associated with source identifier 210 d and routing identifier 212 d) can be processed and stored in the partition 214 of the system database 108 in substantially the same manner as described above. In some examples, the system database 108 can be partitioned to include partition 214 or any other partition in response to scaling out the system 100 to include the load balancer device 202, application server group 204, application servers 206 a-d, and database server 208.

In this manner, the system 100 can be scaled out to include additional or alternative components (e.g., load balancers, application server groups, application servers, database servers, etc.)

FIG. 3 is a flow chart depicting an example of a process for partitioning data in a clustered database environment according to one example of the present disclosure. In some examples, the steps in FIG. 3 may be implemented in program code that is executable by a processor, for example, the processor in a general-purpose computer or a server. In some examples, these steps may be implemented by a group of processors or servers. In some examples, one or more steps shown in FIG. 3 may be omitted or performed in a different order. Similarly, in some examples, additional steps not shown in FIG. 3 may also be performed. The process 300 of FIG. 3 is described with reference to FIG. 1, but other implementations are possible.

In block 302, data is obtained from a data source 10 a-c, along with a source identifier and key identifier of the data source 10 a-c. The data source 10 a-c can be any data source. For instance, the data source 10 a-c can be a meter device for measuring consumption of a resource, such as electricity, gas, water, etc. The data source 10 a-c may measure or receive (e.g., obtain) data, store the data, and communicate the data to a server 102 a-d. The data can include information measured or received (e.g., obtained) by the data source 10 a-c, along with a source identifier or a key identifier associated with the data source 10 a-c. As an example, the data source 10 a is a water meter device and the server 102 a obtains data measured or received by the meter device, along with data indicating a meter device identifier of the water meter device and a particular portion of the meter identifier (e.g., the last two digits of the meter device identifier).

In block 304, a particular application server group 104 a-c associated with the data source 10 a-c is determined based on a routing identifier that corresponds to the source identifier of the data source 10 a-c.

For example, various application server groups 104 a-c can include various application servers 110 a-1. Each application server group 104 a-c can be associated with (e.g., assigned to) a particular routing identifier. In some examples, the server 102 a includes a processor and a memory that includes a database or lookup table 112. The lookup table 112 of the server 102 a can include data indicating source identifiers 114 a-e associated with various data sources 10 a-c and a routing identifier 116 a-e associated with each source identifier 114 a-e. Each routing identifier 116 a-e indicates a particular application server group 104 a-c, application server 110 a-1, or database server 106 a-c assigned to each source identifier 114 a-e. The server 102 a can receive data from the data source 10 a-c, along with the source identifier 114 a-e associated with the data source 10 a-c and the processor of the server 102 a can access the lookup table 112 to determine a routing identifier 116 a-e associated with the source identifier 114 a-e. As an example, the server 102 a receives data from a data source 10 a corresponding to source identifier 114 a and determines that routing identifier 116 a is associated with source identifier 114 a based on the lookup table 112. In this example, the server 102 a can determine that the routing identifier 116 a is associated with (e.g., assigned to) application server group 104 a.

In another example, in block 304, the processor of the servers 102 a-d can determine a routing identifier associated with a data source 10 a-c based on a source identifier of the data source 10 a-c without accessing the lookup table 112. For instance, the sever 102 a can receive data from a data source 10 a-c, along with the source identifier 114 a-e associated with the data source 10 a-c and the processor of the server 102 a can calculate or determine a routing identifier 116 a-e associated with the source identifier 114 a-e and/or the data source 10 a-c using the following formula: Routing Identifier=(Source Identifier % 100)% n

In the equation above, % represents a modulo operation or function (e.g., a determination of a remainder after division of one number by another) and n represents a number of database servers 110 a-1 in the system 100.

In block 306, a particular application server 110 a-1 of the application group 104 a-c that can process the data from the data source 10 a-c is determined. For example, each server 102 a-d can transmit data obtained from a data source 10 a-c to a load balancer device 118 a-c. Each load balancer device 118 a-c can be associated with a particular application server group 104 a-c and communicatively coupled to the particular application server group 104 a-c and the servers 102 a-d. The load balancer device 118 a-c can determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c associated with the application server group 104 a-c. For example, the load balancer device 118 a can be associated with the application server group 104 a and can receive data from the server 102 a. The load balancer device 118 a can determine an application server 110 a-d within the application server group 104 a to process or analyze data from a data source 10 a-c associated with the application server group 104 a. In some instances, the load balancer devices 118 a-c can determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c using various methods or techniques (e.g., in a random manner, based on an availability of an application server 110 a-1 to process data, or any other suitable method or technique). For instance, the load balancer device 118 a can determine that the application server 110 a can process data from a data source 10 a in response to determining that the application server 110 a has available computing or network resources to process the data (e.g., if the application server 110 a is not performing an operation). As another example, the load balancer device 118 a can determine that the application server 110 a can process data from a data source 10 a in response to determining that the application server 110 a has more computing or network resources available as compared to the other application servers 110 b-d of the application server group 104 a (e.g., if the other application servers 110 b-d are performing more operations as compared to the application server 110 a).

In some examples, the system 100 may not include load balancer devices 118 a-c. In this example, in block 306, the servers 102 a-d can determine a particular application server 110 a-1 within an application server group 104 a-c to process or analyze data from a data source 10 a-c associated with the application server group 104 a-c in substantially the same manner as described above.

In block 308, data obtained from the data source 10 a-c is transmitted to the application server 110 a-d of the application server group 104 a-c (e.g., the application server group determined in block 304). In some examples, the servers 102 a-d can be communicatively coupled to the application server groups 104 a-c to transmit data obtained from the data source 10 a-c to the application server groups 104 a-c or an application server 110 a-1 of the application server group 104 a-c. For example, the server 102 a-d can transmit data obtained from the data source 10 a-c to the application server 110 a-1 determined by a load balancer device 118 a-c (e.g., in block 306). In another example, the server 102 a-d can transmit data obtained from the data source 10 a-c to any application server 110 a-1 of the application server group 104 a-c associated with the routing identifier 116 a-e that corresponds to the source identifier 114 a-e of the data source 10 a-c (e.g., the application server group determined in block 304). In some examples, the server 102 a-d can be communicatively coupled to a particular load balancer 118 a-c associated with the application server group 104 a-c and the load balancer 118 a-c can transmit the data to the application server group 104 a-c or an application server 110 a-1 of the application server group 104 a-c.

As an example, the server 102 a receives data from a data source 10 a corresponding to source identifier 114 a and determines that routing identifier 116 a is associated with source identifier 114 a based on the lookup table 112. In this example, the server 102 a can determine that the routing identifier 116 a is associated with (e.g., assigned to) application server group 104 a. Continuing with this example, the server 102 a can transmit data from the data source 10 a to the particular application server group 104 a associated with the data source 10 a or an application server 110 a-d of the application server group 104 a. As another example, the server 102 a can transmit the data to the particular load balancer device 118 a associated with the application server group 104 a and the load balancer device 118 a can transmit the data to the application server group 104 a or a particular application server 110 a-d of the application server group 104 a (e.g., the particular application server determined in block 306).

In some examples, in block 308, the application servers 110 a-1 of the particular application server group 104 a-c can process data obtained or received from the servers 102 a-d or the load balancer device 118 a-c.

In block 310, the data is transmitted to a particular database server 106 a-c associated with the application server group 104 a-c. For example, each database server 106 a-c can be associated with a particular application server group 104 a-c. As an example, and with reference to FIG. 1, database server 106 a can be associated with application server group 104 a, database server 106 b can be associated with application server group 104 b, and database server 106 c can be associated with application server group 104 c. The application servers 110 a-1 of a particular application sever group (e.g., the application server group determined in block 304) can process data obtained or received from the servers 102 a-d or the load balancer device 118 a-c (e.g., in block 308) and transmit the processed data to a particular database server 106 a-c associated with the application server group 104 a-c of the application server 110 a-1. As an example, the application server 110 a can process data received from the load balancer device 118 a or the server 102 a and transmit the processed data to the database server 106 a that is associated with the application server group 104 a of the application server 110 a.

In block 312, the data from the data source 10 a-c is stored in a particular partition of a system database 108 based on the key identifier of the data source 10 a-c.

For example, each database server 106 a-c can include a processor and a memory that includes a database. The database server 106 a-c can receive data from an application server 110 a-1 associated with the database server 106 a-c (e.g., in block 310) and the processor of the database server 106 a-c can access the database to route data received from the application server 110 a-1 to a particular portion or partition of the system database 108.

As an example, the system database 108 can be partitioned (e.g., divided) based on key identifiers associated with various data sources 10 a-c. For example, the system database 108 can be partitioned into partitions (e.g., portions) 120, 122, 124 and each partition 120, 122, 124 can be associated with a key identifier of a particular data source 10 a-c. For instance, partition 120 can be associated with the key identifier of the data source 10 a corresponding to source identifier 114 a, partition 122 can be associated with the key identifier of the data source 10 b corresponding to source identifier 114 b, and partition 124 can be associated with the key identifier of the data source 10 c corresponding to source identifier 114 c. In this example, the database of the database servers 106 a-c can include data indicating key identifiers associated with various data sources 10 a-c and a portion of the system database 108 associated with (e.g., assigned to) each key identifier. The database servers 106 a-c can use the database to route data obtained from a data source 10 a-c (e.g., via a corresponding application server 110 a-1) to a particular portion of the system database 108 that corresponds to the key identifier of the data source 10 a-c. As an example, the database server 106 a obtains data from the application server 110 a that includes data from a data source 10 a associated with source identifier 114 a, along with the key identifier of the data source 10 a. A processor of the database server 106 a access a database of the database server 106 a to determine the particular partition 120 of the system database 108 associated with the key identifier and transmits the data to the system database 108 to be stored in the partition 120 of the system database 108.

While in this example, the system database 108 can be partitioned based on key identifiers associated with various data sources 10 a-c, the present disclosure is not limited to such configurations. Rather, in other examples, the system database 108 can additionally or alternatively be partitioned in any suitable manner and the database servers 106 a-c can be configured to transmit data to the system database 108 to be stored in a particular partition of the system database 108. For example, the system database 108 can be partitioned based on a date, time, or any suitable interval and the database servers 106 a-c can be configured to transmit data to the system database 108 to be stored in a particular partition of the system database 108 based on a particular date, time, or interval. As an example, data stored in the system database 108 can be additionally partitioned based on days in a month and the database servers 106 a-c can be configured to transmit data to the system database 108 to be stored based on the partitions such that data obtained from a data source 10 a-c is stored in a particular partition of the system database 108 associated with a key identifier of the data source 10 a-c, as described above, and the particular partition is further partitioned based on the day of the month that the data is received (e.g., data received from the data source 10 a-c on a particular day can be stored within a sub-partition of the partition). As another example, data transmitted or stored in the system database 108 can be additionally or alternatively partitioned based on any suitable criteria such as a type, content, characteristic, etc. of the content from the data source 10 a-c.

While in the examples described above, data from a data source can be routed and partitioned based on a source identifier, routing identifier, or a key identifier associated with a data source, the present disclosure is not limited to such configurations. Rather, in other examples, data from a data source may be routed to a particular server, load balancer device, group of application servers, and/or database server based on a source identifier, routing identifier, or a key identifier associated with a data source.
